Title: Clutch release bearing assemblies
IPC: F16D23/12
Filed: 1980-12-19
Abstract: A release bearing assembly for a pull type clutch and which includes a stem attached to the stationary race of its bearing and which is accommodated between two arms of a release fork.

Patent ES-8303961-A1 (ES)
Title: Vibration damped portable impact tool
IPC: B25D17/24
Filed: 1982-06-23
Abstract: A vibration damped portable impact tool comprising a pneumatically powered reciprocating mechanism to which a chisel is connected. In the disclosed tool the chisel is rigidly connected to the piston of the reciprocating mechanism so as to move conjointly therewith. The drive mechanism is arranged in a previously known manner to absorb its own acceleration forces whereby the only vibration forces acting on the tool derive from the chisel in its contact with the work piece. By adapting the spring constant relating to bending of the chisel to the entire mass of the tool such that the resonance frequency of that system is lower than the impact frequency, the vibration forces arising at the working end of the chisel are not transmitted to the tool housing.

Patent ES-8603220-A1 (ES)
Title: Pipe fitting.
IPC: F16L41/02
Filed: 1983-05-13
Abstract: The invention relates to a pipe fitting A, B, C with flange connection for joining at least two pipe ends angled with respect to each other, suitable for the installation of a pipe system of desired configuration with branchings and/or elbows. The pipe system to be installed has to have the capacity to be installed in the smallest possible space and with the most sharp and twisted bends in any desired direction. According to the invention this problem is solved by molding an annular rim flange (3, 4, 14, 15, 16) extending over the surface of the fitting to at least one of the connection openings (1, 2, 11, 12, 13) angled towards each other by at least 45 DEG of the arch-shaped fitting (A, C) and by the fact that the flange projection and the inner curvature of the pipe fitting (A, C) are mutually coordinated in such a way as to barely allow the positioning on the flange of a clamping collar (F) by means of which the rim flange is directly pressable against a counterflange. The rim flange must therefore be shaped on its outside and at its frontal surface so that on the one hand it can receive a sealing means and on the other hand it still has enough elasticity with respect to the outer wall of the pipe when the flanges are pressed together by the clamping collar (F) engaging over them. For this purpose a groove for receiving the sealing means and a circular recess at the base of the rim flange in the frontal area are provided, serving as theoretical bending point.

Title: Four-quadrant gate-sizing technique.
IPC: H04N7/18
Filed: 1984-03-30
Abstract: A four-quadrant frame of reference, established with respect to a sensed target image, effectively converts the image into a composite target regardable as the union of four, quadrant-based target-segments. Four subgates, each established within a different reference-frame quadrant, become in union a composite tracking gate. As the effectualization of the actual gate-sizing, the degree of conformity between the composite gate and the composite target is then optimized by optimizing the degree of conformity between the subgates and the associated target-segments.

Title: Apparatus for controlling gear changing operation in automatic transmission.
IPC: B60W10/10
Filed: 1984-06-29
Abstract: A method of controlling the gear changing operation in an automatic transmission having a gear transmission actuatable by a gear changing actuator assembly controlled by an electronic control system.
